Industrial drill bits custom fabricated from a 20ft pipe, carbide teeth were welded with hardfacing rods. Welded the carbide bits for reinforcement under extreme pressures. The drill bits where tack welded into place, followed by a root pass weld and filled in with a second weld pass. The Welds were inspected by a certified welding inspector.

We traveled to the US/Mexico Border in Otay Mesa, San Diego to some welding work on an industrial sized X-ray machine used to scan vehicles like semi-trucks, vans, and cars, passing through the border. The task was to reinforce the radiation barrier by ARC welding a 3/4? X 12? x 36? steel plate. This will keep the X-ray(s) produced by the machine from penetrating the radiation barriers. We beveled the plates to insure a tight fit and tack welded them into place. The x-ray technician ran some test to make sure the steel plates where in the correct position. We welded several beads with 7018...
